help with ses, how do i fix?

[gunter96ws6]

ok i was comming home from work and im hearing these wierd noises comming from the back of the car, honestly sounds like the rear speakers are makeing a poping noise. or like i have pieces of bricks in the cargo area and they are slaping around, but its not when i hit a bump its just random. then the ses light somes on so i go ahead and drive to auto zone to see what the code is, the code says o2 sensor low voltage (bank 2 sensor 2) what does this mean? i would like to add that i just got hooker long tubes, pcmforless tuning and yesterday i got my 3" y pipe and exhaust put on, thanks for any and all help~gunter

Did you change the o2 sensors when you put the headers on? Assuming that you're still even running o2 sensors instead of simulators, it could very well be that you need to replace your o2 sensors. It might be a good idea to change them all while youre down there instead of just one.

i extended the front o2s and and have simulators in the post-cat ones~gunter

Sensor 2 means one of your after cat 02 simulators is not functioning properly. Sensor 1 is your reagular 02 sensor, proir to the cat. Sensor 2 is after cat.

With the sounds you heard, it could be that your cat's guts disintegrated...(I hate it when that happens, to a car type cat that is! ).

i doubt it seeing as how i havnt had cats in about 8 months, any other suggestions?~gunter

Oh...yea...DOH!!

OK, how about this for a long shot.... one of your post cat sensor/simulator wires melted or wore through rubbing on something and the sounds you heard really were comming from the speakers because of interference in the elictrical system as a hot wire to the sim grounded out? (Whew...long sentance )

Have a great weekend! I'll leave this one alone now.
